For use in various industrial sectors

Construction

Due to its chemical and physical properties, calcium carbonate has a wide range of applications across various industries, especially in the paint and coatings industry, adhesives, mortars, ceramics, and cement-based products. Calcium carbonate used in construction provides products with resistance, pigment properties, strength, viscosity, and mechanical performance. Micronized calcium carbonate plays a key role as a filler in paints and coatings. Natural limestone (calcium carbonate) is a primary raw material for binding and sealing products. From the finest powder to granules, calcium carbonate has a broad application in the construction industry. When CaCO₃ is added to concrete, it enhances self-compacting properties, resulting in improved workability, increased strength, and a better appearance with a smooth surface.

Animal nutrition and health

Calcium is one of the essential nutrients in all types of animal nutrition, including pigs, poultry, ruminants, and even pets. The main functions of calcium in animal nutrition are: - proper growth and development of bones and teeth - regulation of heart function and blood clotting - activation of enzymes and hormone secretion - eggshell formation - increased milk production and reduced risk of milk fever - muscle contraction and nerve impulses - activation of enzymes and hormone secretion Ground limestone (calcium carbonate) typically contains between 36% and 38% calcium, while the limestone from our quarry has an even higher calcium content—up to 40%. Regular quality control is conducted at the SP Laboratory in Bečej, where the presence of heavy metals and the calcium percentage are monitored.

Flexible polyurethane foams

Flexible polyurethane foams are one of the most important classes of cellular plastics used in the production of materials such as sponges, memory foams, pillows, furniture, automotive upholstery materials, packaging, footwear, and more. The total consumption of flexible polyurethane foam was estimated at over 7 million tons in 2007, with an average annual growth rate of about 5%. In general, industries that manufacture flexible polyurethane foams use fillers to modify the properties of the material in specific ways to achieve dimensional stability, easy mold release, and service density. The production cost of flexible polyurethane foam largely depends on the cost of polyols, which make up the highest percentage of the materials used in foam production and are characterized by their ability to induce superior mechanical properties. Suitable fillers that are relatively inexpensive can be incorporated into the foam matrix as a replacement for polyol. The influence of CaCO₃ filler in the flexible polyurethane foam matrix serves a dual purpose of achieving sustainable mechanical properties and reducing production costs. It was found that the optimal composition of CaCO₃ is 20 wt.%, which simultaneously represents a production cost reduction of 18.54%. In flexible polyurethane foams, fillers promote an increase in density and compression resistance.

Plastics industry

DUCALCIT – The importance of calcium carbonate in various industrial sectors, with a special emphasis on its use as a filler in the polyvinyl chloride (PVC) industry. Among all fillers used in PVC processing, 80% are calcium carbonate-based. Fillers are used to improve various mechanical properties of polymers such as tensile and breaking strength, density, hardness, thermal stability, viscosity, and more. The latest trends in industrial development, as well as the demands of the processing industry for higher-quality carbonate fillers, have led to the introduction of surface modification processes for limestone (calcite)—the main component of finely micronized limestone—in order to enhance its properties. DUCALEN is an eco-friendly masterbatch – a filler in granule form with a high content of selected ultra-fine natural calcium carbonate blended into an LLDPE carrier with a slip agent. DUCALEN is mainly intended as an additive for film-blowing extrusion, and is also used in injection molding, thermoforming, pipe extrusion, and similar technologies.DUCALEN increases productivity and reduces extrusion pressure, improves dimensional stability, shortens cooling time and cycle duration in the injection molding process, enhances mechanical properties, and lowers the cost of the final product.

Agriculture, fisheries, and forestry

Calcium, an essential element in the nutrition of cultivated plants, is found in the soil in non-replaceable forms within various minerals such as calcium carbonate, calcite, dolomite, calcium phosphates, apatites, and silicates. These forms of calcium are inaccessible to plants until they decompose and dissolve, at which point they can be absorbed. Due to the intensive use of soil and the insufficient addition of calcium through fertilizers, calcium is often completely depleted from the arable layer. This leads to increased soil acidity (a decrease in pH value), which in turn causes the breakdown of the soil's complex structure, leaching of other nutrients, deterioration of soil structure, and, naturally, a lack of calcium as a biogenic element for cultivated plants. Calcium is removed from the soil through the yield of cultivated plants, and once it becomes available in a soluble form, it is practically unprotected from leaching. As a result, most of our soils, which were once rich in calcium, are now depleted of it in the arable layer. The only corrective measure, or neutralization of such soils, is the application of **liming**.

Water treatment

Zeolites are a group of natural minerals that possess certain properties enabling them to exchange one charged ion present in their crystal structure for another ion present in the environment. Zeolite is an effective remover of ammonia and also provides a large surface area for nitrifying bacteria in recirculating systems. Zeolite not only provides optical water clarity but also keeps it biologically clean. Key benefits: • absorbs toxic ammonia • absorbs heavy metals and pesticides • removes micro particles from water • reduces algae growth • prevents the spread and concentration of unpleasant odors in water supply facilities • prevents the development of microorganisms and decay in water • will not cloud the water • non-toxic • completely safe for fish and nitrifying bacteria
